Original Abstract

In this paper, an original design of a range illuminator based on a stepped septum polarizer and a dual mode horn is discussed. However, the designed polarizer can be used with other wave-guide antennas as well, e.g., pyramidal horns, corrugated horns etc. A simple procedure for determining the initial septum ge-ometry for the subsequent optimization is described, and based on this, a two-step septum polarizer is developed. A carefully designed dual mode horn antenna with a rectangular aperture is then utilized to increase the illuminator's gain and to suppress sidelobe levels. Results of full-wave electromagnetic simulations are presented and compared to experimentally measured data with good agreement.
